Patent CA-2322366-A1 (CA)
Inventor: POTTER JAMES CLIFTON
IPC: G05D16/20
Filed: 2000-10-05
Abstract: A variable force solenoid operated pressure control valve for controlling an hydraulically operated actuator in a fluid pressure circuit. The valve has a spool in a straight spool bore with fluid pressure chambers at opposite ends. One spool end has a rod press fitted therein with the rod extending through the fluid pressure chamber and operatively contacting the solenoid armature. The rod creates an area differential on the spool ends for providing an axial spool force proportional to the pressure in the fluid chambers which are each connected by a metering passage in the spool to a recess on the spool which is continuously connected to a control pressure port. A supply port is connected to the recess by a first valuing land on the spool and an exhaust port is connected to the recess by a second valuing land on the spool. The metering passages serve to attenuate transients.

Abstract: Proximity sensors (23, 24) for detecting an object by generating AC magnetic fields having different frequencies upward and by allowing the energy to be lost by the current generated by the AC magnetic fields are provided at the fore end of a transport electric car (V). A decelerator/stopper (W) forming two resonance circuits resonating at the frequencies of the proximity sensors (23, 24) is opposed to the proximity sensors (23, 24) at the side portion of a guide rail (B). A detection plate (25) for prevention of rear-end collision is provided at the rear end of the car (V). The detection plate (25) can enter the space between the first proximity sensors (23, 24) and the decelerator/stopper (W). Thus, no through hole made in the guide rail for wiring is needed unlike conventional guide rails when installing the decelerator/stopper (W) on the guide rail (B), thus facilitating the installing work.

Title: Method for fingerprint verification using a portable device
Inventor: SOUTAR COLIN
IPC: G06K9/00
Filed: 2001-03-14
Abstract: The invention describes a method for fingerprint verification using a portable device with low data memory requirements and low power consumption. The enrollment part of the method includes sorting information contained in a fingerprint image into alignment information and verification information. The latter may comprise a set of "tiles" extracted from different parts of the image in the pre-determined locations, the size of said "tiles" and of the alignment information being considerably smaller than of the entire image. An optimization procedure including, in particular, generating a composite filter, may be applied to create an enrollment template. The verification part of the method includes extracting alignment information from a candidate image, utilizing said alignment information to align the candidate image with the enrolled one to obtain the adjusted "tile" locations for the candidate image. The next step includes extracting the "tiles" of the same size and orientation as on the enrollment from the candidate image and matching each "tile" with the corresponding "tile" on the enrollment. A  set of matching parameters is obtained for each "tile". The final match/non-match decision is based on multivariable decision boundaries approach. Since the alignment information and each "tile" is processed in a consecutive way, the memory and, accordingly, the power consumption requirements for the hardware are significantly reduced.  This allows the invention to be used with a portable device.

Patent CA-2363897-A1 (CA)
Inventor: SOGA HISASHI
IPC: B60Q3/02
Filed: 2001-11-28
Abstract: Conventionally, in order to downsize the enclosure, there was no other choice than downsizing the enclosure and decreasing the area of the lens plate, or increasing the area of the lens plate and increasing the enclosure as well. However, decreasing the area of the lens plate disadvantageously lowers brightness of illumination. In contrast to this, when the dimensions of the lens plate are increased, the proportion of the area of the lens plate with respect to the roof increases, which leads to a problem in terms of design. Accordingly, the present invention provides an interior light system for vehicles comprising a lamp accommodated in the enclosure, a push switch for turning on and off the lamp fixed in the enclosure, and a lens plate journaled at the ends of the opening of the enclosure for a swinging motion, in which the push switch is turned on and off by pressing the lens plate, thereby turning the lamp on and off.

Abstract: A driving apparatus has a roller screw member that includes a main shaft, a plurality of roller shafts projecting radially outwardly and upwardly at an angle from the radial direction of the main shaft and arranged along a helical line there around, and a plurality of rollers rotatably mounted on the roller shafts. The rollers are tapered to the same angle inwardly toward the main shaft. A rail member, adjacent to and axially oriented with the main shaft, includes a plurality of spaced projections adapted for radial engagement with the tapered rollers. The angle of the tapering is pre-determined to provide a sliding free engagement between the rollers and the projections with the interface there between being oriented to intersect the rotation axis of their respective roller shaft on the rotation axis of the main shaft. The rotation of the main shaft axially moves the roller screw relative to the rail member.
